我正在为我的投资组合网站创建一个CMS项目.我无法使更新功能正常工作.我觉得它与我构建PDO事务的方式有关.在我的数据库中,我有一个项目表,类别表和关联的content_category表.我能够很好地将我的项目插入到这些表中.我想要做的是插入我的项目表然后删除content_category表中的所有记录,最后将当前类别记录插入到该关联表中以完成事务.我确实得到了返回声明"Project Updated".但表格没有更新.任何人的想法？

这是代码:

这是我的Project类中的一个函数.

public function update(){
    try {
        $conn = getConnection();
        $conn->beginTransaction();
        $sql = "UPDATE project 
                SET project_title = :title, 
                    project_description = :desc, 
                    project_isFeatured = :feat, 
                    project_mainImage = :image
                WHERE project_id = :id";
        $st = $conn->prepare($sql);
        $st->bindValue(":id", $this->id, PDO::PARAM_INT);
        $st->bindValue(":title", $this->title, PDO::PARAM_STR);
        $st->bindValue(":desc", $this->description, PDO::PARAM_STR);
        $st->bindValue(":feat", $this->isFeatured, PDO::PARAM_BOOL);            
        $st->bindValue(":image", $this->mainImage, PDO::PARAM_INT);
        $st->execute(); 

        $sql = "DELETE from content_category
                WHERE content_id = :id";
        $st = $conn->prepare($sql);
        $st->bindValue("id", $this->id, PDO::PARAM_INT);
        $st->execute();

        $sql = "INSERT into content_category (content_id, cat_id)
                VALUES (?,?)";
        $st = …

我正在尝试用Laravel实现分页,我的分页链接在网页上显示为原始html.我对Laravel很新,我不确定我哪里出错了.我正在使用Laravel 5.

UserController的@指数:

public function index()
    {
        $page = \Input::get('page', 1);
        $data = $this->user->getByPage($page, 10);

        $users = Pagination::makeLengthAware($data->items, $data->totalItems, 10 );

        return view('admin.users.index', compact('users'));
    }

EloquentUser getByPage方法:

public function getByPage($page=1, $limit=10)
    {
        $result = new \StdClass;
        $result->page = $page;
        $result->limit = $limit;
        $result->totalItems = 0;
        $result->items = [];

        $users = $this->user->skip($limit * ($page - 1))
                       ->take($limit)
                       ->get();

        $result->totalItems = $this->user->count();
        $result->items = $users->all();

        return $result;
    }

分页服务:

<?php namespace App\Services;

use Illuminate\Pagination\Paginator;
use Illuminate\Pagination\LengthAwarePaginator;

abstract class Pagination
{
    /**
